Subaru's next-generation Impreza has broken cover ahead of an official debut at the 2016 New York motor show.

The compact four-door sedan and hatch features a more sharply styled, premium look that brings it closer in line with performance models such as the WRX and BRZ.

Subaru's entry-level model rides on a new platform that will become the basis for all of its four-door models in coming years, with the next-gen XV, Liberty, Outback and Forester set to share its architecture.

It is a little larger than its predecessor, with a longer wheelbase that should translate to improved cornering stability and more interior space.

The brand has not released technical details surrounding the model, which is likely to feature clever EyeSight driver aids along with a family of horizontally opposed "boxer" four-cylinder engines and all-wheel-drive.

Subaru Australia spokesman David Rowley says the new Impreza is set to arrive locally in December. It will be followed in 2017 by a new XV, though Rowley says high-performance WRX and STI spinoffs are "quite some time away".
